Trait MapProblemOr

pub trait MapProblemOr {
    type ProblemCarrier;

    // Required methods
    fn map_problem_or(self, problem: impl Into<Problem>) -> Self::ProblemCarrier;
    fn map_problem_or_else<F, P>(self, problem: F) -> Self::ProblemCarrier
       where F: FnOnce() -> P,
             P: Into<Problem>;
}

Map type not containing any error to type containing given Problem

Required Associated Types

type ProblemCarrier

Required Methods

fn map_problem_or(self, problem: impl Into<Problem>) -> Self::ProblemCarrier

fn map_problem_or_else<F, P>(self, problem: F) -> Self::ProblemCarrier

where F: FnOnce() -> P, P: Into<Problem>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
